Conventionally, in this type of multi-chip package, wire bonding or TAB (Tape Automatic Bonding) has been used as a structure for mounting and connecting ICs on ceramic substrates with polyimide insulation (for example, ``Copper/Tape Automatic Bonding for High Performance Mounting''). Polyimide material system (COPPER/

Conventional wire bonding as mentioned above or
In the TAB connection structure, since the lead terminals are connected outside the external dimensions of the IC or LSI chip, the mounting efficiency decreases, and the use of thermocompression bonding or ultrasonic waves deforms and destroys the polyimide insulation on the surface, reducing reliability. It has the disadvantage of decreasing the Or, in a soldered connection structure, the size of the connection pad or connection bump cannot be less than 50μ. This has the disadvantage that high-density packaging is impossible.
